Question

A computer is unable to access the network. When you check the LED lights near the computer's network port, you discover the lights are not lit. Which layer of the OSI model are you using to troubleshoot this problem? At which two layers does the network adapter work?

Answer 1

Answer:

Link layer and physical layer

Explanation:

The Link layer and the physical layer -

It is the very lowermost layer in the networking architecture of the internet i.e. the internet protocol suite , is referred to as the link layer.

The description of the link layer is RFC 1122 and RFC 1123 .

The link layer refers to the communications protocols and the group of method which operates only when the host is physically connected to it.

The physical layer  -

In the OSI model , it is the first layer .

Answer 2

The layer of the OSI model that will be used in troubleshooting this problem will be the physical layer.

The two layers where the network adapter work will be the physical layer and the data link layer.

It should be noted that the physical layer refers to the layer that helps in converting bit into signals. It's also important for defining connectors and media.

The layer 2 of the OSI model is the data link layer. It's vital for managing access to a network.
